Hi Ralph, --What do you want to log? I want to log value with Timestamp. My record scanning rate is 1 Second and i want to log at same rate. I also have some PV having I/O Intr. in that case at the time of value change. For outputs: Value change by operator. and want to log the changed value with time. -- How long do you want to log? (just during a test setup? over long periods? forever?) It should be log value it IOC run. we can say forever. -- What do you want to do with the information? (use it for debugging? create plots of values over time?) - it can be used for analysis and create plots. -- Where do you want to log? (local on IOC console? remote on a different, maybe central, server?) locally may be in some file etc. Thank you very much.

The answer depends on: - What do you want to log? (value? timestamp? alarm status? For outputs: also who changed it? from where? old and new value?) - How long do you want to log? (just during a test setup? over long periods? forever?) - What do you want to do with the information? (use it for debugging? create plots of values over time?) - Where do you want to log? (local on IOC console? remote on a different, maybe central, server?) If you supply a more complete specification of your request, people will be able to point you to the best solution. Thanks, ~Ralph
